for 6694...bottom dollar they usually go for around usd1k...
of cos other factors come into play...like yr...color...box etc...but thats the bottom.
so like 3yrs ago u could easily buy a 6694 for rm3k+ here...now with the currency rate obviously no longer rm3k+.

best way to find out... call rolex center... ask them how much is it to replace the dial...the price should be a very good indicator if it's real gold or not.

its 15% now?
last time i remember 5% only.
must be too many taking advantage...buy...wear for 1 month to grow e-penis...then return
